5.2.4 EMC Compliant Electrical Installation
General points to be observed to ensure EMC-correct electrical installation.
Use only screened/armoured motor cables and screened/armoured control cables.
Connect the screen to earth at both ends.
Avoid installation with twisted screen ends (pigtails), since this ruins the screening effect at high frequencies. Use
the cable clamps provided instead.
It is important to ensure good electrical contact from the installation plate through the installation screws to the
metal cabinet of the frequency converter.
Use starwashers and galvanically conductive installation plates.
Do not use unscreened/unarmoured motor cables in the installation cabinets.
